I don't second guess juries and his got it right, but his actions since then have been stupid. Flip it around and if he had been convicted, but found a way to do charity work from prison would we really say, "See he's a good guy and was innocent" ?
One situation is just that and should be judged on its own. oh by the way, I; would bet a good case could be made for him having some form of PTSD. (No junior it isn't just a veteran's issue)
As a result of the Martin incident his whole life changed and he isn't handling it well. It has happened to people before. Put a few miles in his moccasins . Very few people judging him now have ever killed a man and been in such a public circus.
